Maximum number of chars in one single cmdLine parameter

[DHL]

The help file says that a "maximum number of 63 parameters can be returned by the array $CmdLine[]". (https://www.autoitscript.com/autoit3/docs/intro/running.htm)

But how many characters can one parameter have at the most? 

Say I'm creating a script where i input two file-paths in one single command line parameter (delimited by some none-filepath character, like "!"). Do I need to worry about the length of that specific $cmdLine[x] input parameter (string) being too long for AutoIt?

As Windows can only handle filepaths up to 255 characters you do not have to worry.

Just make sure you enclose them in quotation marks in case the path contains spaces.

BTW: Why concatenate two paths? Can't you simply use two parameters?

There is no limitation that I can think of, though share the same point of view as water.

Thanks for the fast replies, water and guinness.

Water, Yes - I could use two parameters. I'm playing around with some stuff and the example was more a hypothetical than a practical problem. 

But thanks :-)
